MATLAB: How to create a function of matrix with integer(from 1 to infinite) that can be arranged by row and column

functionloopmatrixrow

for example, if m=2, n=3 then the matrix become [1 2,3 4,5,6]' if m=4 n=4 it is [1 2 3 4,5 6 7 8,9 10 11 12,13 14 15 16]' I know I should use loop, but where should I start it? i think i may need some help here…it asks one output and two inputs.

Depending on the orientation you are after, either:

reshape(1:m*n,m,n)

reshape(1:m*n,n,m).'

A = reshape(1:18,3.,[])';
N=2;
M=2;
[~,n] = size(A);
A2 = reshape(kron(reshape(A',n*N,[]),ones(1,M)),n,[])';

In case that is the pattern you're looking for, here is the code that implements it:

function M=create_stairs_matrix(N)
M=zeros(N,1);M(1)=N;n=1;%prepare for loop
while M(n)>1
    %halve number of elements (rounding up) until 1 is reached
    M(n+1)=ceil(M(n)/2);
    n=n+1;
end
M((n+1):end)=[];%remove empty rows
nonzeroelems=sum(M);
%mark the number of elements to be filled with a true
M=(1:N)<=M;%implicit expansion (use bsxfun on <R2016b)
M=double(M');
M(logical(M))=1:nonzeroelems;
M=M';
end
